Build a drafting combination

A registered straight line, plus the angles you use

A T-square establishes the board-edge reference. A triangle rests against its blade to guide perpendiculars and the triangle’s stated angles. Add the second geometry only if your drawing calls for it.

Individually sold tools, not a manufacturer-prepacked kit. A drawing board, paper, pencil and fasteners are not included. Confirm each selection below before adding; changing a size never adds anything automatically.

PRODUCT GUIDE

Choose and use this instrument with confidence.

Choose a wider-blade aluminum T-square for a supported large-format drawing or layout surface.

The fixed head registers to a straight work edge to establish a perpendicular reference. This family offers 24–72-inch configurations with a wider blade and longer head than the standard family’s documented sizes. One selected T-square is supplied; a board, paper, pencil and triangles are separate. A longer tool is not useful unless the working surface supports the required span.

Choose the right configuration

Catalog options are 24, 30, 36, 42, 48, 60 and 72 inches; live availability varies. Choose the exact SKU below and review its dimensions and shipping. Long selections can use an oversize profile. The family photograph shows the 24-inch tool, not an exact photograph of the 60- or 72-inch configurations.

Product details

  • Material: Aluminum blade; green ABS head
  • Finish: Anodized aluminum
  • Measurement system: English
  • Graduations: Blade: 1/8 and 1/16 inch; head: 1/8 inch

Care, warranty, and returns

Store flat or fully supported so the measuring body, square head, or curve is not bent or twisted. Wipe with a soft dry cloth after use; if a lightly damp cloth is needed, dry the instrument immediately. Lance instruments include a 30-day warranty. Returns are accepted within 30 days when the product is unused.

Register the head. Draw along the blade.

Schematic T-square: head rests against the left board edge; blade guides a horizontal line perpendicular to that edge Straight board edge Draw along the blade Keep the head in contact Support the blade and drawing surface

Original schematic. Not a measured product photograph, dimensional specification or certification of squareness.

Use the board edge as the reference

  1. Check that the board edge is straight and the drawing is secured. A bowed or damaged edge is not a reliable reference.
  2. Hold the T-square head against that edge with the blade resting on the work surface. Keep the same registration as you move it.
  3. Draw in pencil or pen along the blade. A triangle can rest against the blade to guide its own stated angles; keep both contact edges seated.
  4. Choose blade length to cover the required drawing span from the board edge without unsupported overhang. A longer blade does not correct an unsuitable board edge.

Need two measured pattern axes without a board-edge reference? An L-square is a different alternative, not the method shown here.

Check the selected length, documented blade/head dimensions, availability, price and shipping at the purchase controls. These tools are not presented as knife/rotary-cutter guides.

Suitable for / not documented for

Suitable for

  • Drafting
  • Perpendicular layout

A T-square registers its head against a straight board edge to guide a perpendicular line. For two measured pattern axes without a board-edge registration, compare an L-square.

Not documented for

  • Tolerance-critical inspection: Accuracy and tolerance are not yet documented for this product family and size.
  • Knife or rotary-cutter guide: No cutting-safe edge specification is documented.

Use these guides for pencil/pen marking. Do not run a knife or rotary blade against a calibrated edge without confirmation that the selected SKU is designed for that use. Slip-resistant backing alone does not establish blade compatibility.
